* **Slot**: The smallest time unit in the L1X blockchain, where one block is created every 0.5 seconds.
* **Chunk**: A 20-second time interval consisting of 40 slots in the L1X blockchain, organizing blocks for efficient management and synchronization.
* **Epoch**: A period in the L1X blockchain comprising consecutive 3 chunks, typically lasting for one minute, during which clusters propose blocks and facilitate network consensus.
* **Cube:** A unit of time in the L1X blockchain that encompasses multiple epochs, typically lasting for three minutes, incorporating cluster shuffling and providing milestones for network analysis and planning.
* **Radix:** a node that serves as an entry point for new nodes, providing network information, cluster assignment, and maintaining thresholds for participation.
* **Validator**: a node that validates transactions, secures the network, and can be selected as block proposers through a pseudo-random algorithm based on the stake and other factors.
* **Block Proposer:** a node responsible for creating new blocks and proposing them to the network for validation.
* **Vigilant Node**: a node in a blockchain network that monitors transactions, and detects and reports malicious activity to the block proposer.
